REEL AND SPINLLE MOUNT THEREFOR.

Application filed March 8, 1923. Serial No. 623.689.

To all whom it may concern:

Be it known that I, ALBERT S. HOWELL, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful improvement in Heels and SpindleMounts 'lhcrefor, of which the following isa full, clear, concise, andexact description, reference being had to the accompanying drawing,formii'ig a part of the specification.

My invention has particular relation to reel and spindle mounts of thetype usually employed on motion picture machines although not limited tothis use alone.

One feature of the invention relates to a simple and effective means forpreventing reverse mounting of a reel on a spindle.

Another feature relates to a simple, coinpact, and effective releasablespring latch equipped spindle for releasably maintaining a reel on thespindle.

With these features in view my invention consists in certain features ofnovelty in the construction, combination and arrangement of parts bywhich the said features and certain other features hereinafter appearingare effected, all as fully described with reference to the accompanyingdrawing and more particularly pointed out in the claims.

In the said drawing i igure 1 is a side elevation of a spindle mountstructure with a reel shown in central vertical section, mountedthereon.

Figure 2 is a partial front elevation of the spindle mount structurewith a reel mount ed thereon.

Figure 3 is an enlarged partial central vertical section of the same.

Figure 4 is a partial perspective view of the spindle.

Figures 5 and 6 are partial views of opposite sides of the reel.

Like characters of reference indicate like parts in the several views.

In the said drawings 1 designates a support arm, and mounted forrotation in a hub of this arm is a spindle 2, the reel mount I portionof which extends outwardly from one end of the hub. This extendingportion of the spindle is provided with a longitudinally varied reelmount surface comprising a round outer portion 3 and a square orpolygonal inner portion l having its faces tangential to the roundportion and accordingly extending laterally beyond the round portion andterminating in an outwardly facing shoulder 5.

The reel includes spaced side plates 6 and T secured in a usual mannerto opposite ends of a central tubular member 8, and the side plates 6and 7 are provided respectively with central coaxial spindle apertures 9and 10 forming a spindle opening. The spindle aperture 10 of the plate 7is round corresponding with the outer portion 3 of the reel mountsurface of the spindle to fit over the same in the mounting of the reelon the spindle, and the aperture 9 of the plate 6 is square or polygonalcorresponding with the inner portion 4 of the reel mount surface of thespindle to fit over the same in the mounting of the reel on the spindle,the sides of the square or polygonal aperture 9 being in planestangential to the round aperture 10, and, as shown, the length of thesides of the square aperture 9 being the same as the diameter of theround aperture 10, see Figs. 5 and 6, thus forming a longitudinallyvaried spindle opening corresponding with the longitudinally varied reelmount surface of the spindle. It is an inherent characteristic of a reelwith such apertures that it will fit over and rotate satisfactorily on aspindle which is cylindrical throughout, such as one having throughoutthe same diameter as portion The reel is mounted on and removed from thereel mount portion of the spindle over the outer end thereof, and byreason of the fact that the aperture 10 of the plate 7 will not fit overthe portion 4 of the reel mount surface of the spindle, the reel canonly be mounted on the spindle in one way, i. e., with the plate 6,having the spindle aperture 9, inward as shown. The engagement of theaperture Jot the plate 6 with the portion l of the reel mount surface ofthe spindle provides for driving the reel from the spindle.

When the reel is mounted onthe spindle the inner surface of the plate 7,forming a shoulder surface, engagesthe shoulder 5 of the spindle tolimit inward movement of the reel. The reel is releasably maintainedagainst outward movement by means new to be described. The reel mountportion of the spindle is bored from the outer end thereof as designatedat ll. and is provided with a radial aperture 1; eonnnunieating with thebore of the spindle and disposed at a point adjacent the position of theplate- 6 the portion. 4: of the reelinount surface of the spindle, andthe arrangement is such that this portion of the spring is disposed infront of the inner plate (5 of the reel when the reel. is mounted on thespindle and maintains the reel against outward movement on the spindlewith the outer plate 7 against the shoulder 5. The spring is depressedto permit the plate 6 to ride over the same in both the mounting of thereel and the removal thereof by excess axial pressure eX-- ert ed on thereel in the proper direction.

lVhile I have herein shown and particularly described the preferredembodiment of myinvention I do not wish. to be limited to the precisedetails of construction shown as changes may readily be made withoutdeparting from the spirit of my invention,
